SPIRIT- LEVEL.

SPECIFICATIONv forming part of Letters Patent No. 250,061, dated November 29, 1881.

Application tiled May 19, 1881.

To all whom it may concern:

Be it known that I, GEORGE EGART, of' Mooleyville, in the county ofBreckinrid ge and State of Kentucky, have invented a new and useful Improvement in Spirit-Levels, which im provement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a side elevation of the level, and Fig. 2 is a top view of the same.

The object of my invention is to improve the ordinary spirit-level, and it consists in having a frame for the tube containing the spirits, so constructed that the tube can readily be re moved,and so that the tube, when placed in its position, can be revolved or turned face downward, so as to prevent liability ot breakage by contact with surrounding objects.

In `the accompanying drawings, A represeuts the wood-work of the level, having a recess, B, cut out at the top edge centrally. This recess is covered by the usual edge or facing plate, G. Depending downward from the plate C at'one end ot the recess B is a bracket, G.

and at the opposite end ofthe recess is a block, E, secured to the plate C bv means of a setscrew, L, so that the block E may be raised or lowered a limited distance for purposes which will be hereinafter fully explained.

A vertical bar, D, extending downward from the block E to,near the bottom ot the recess, is bent to assume a horizontal direction, and extends along the bottom of the recess to the opposite end, where it terminates in a right` angled upward extension, F, which is secured to the bracket G.

The tube H, preferably made ot' metal, is provided at one end with a screw-threaded socket-r adapted to receive the screw I, which passes through the vertical arm D. The opposite end of the tube has ajournal, H', soeketed in the upright F. rlhe tube is further provided at this end with a wheel, J, provided ou two opposite sides with notches J'. Aspring, L', secured at one of its ends to the horizontal part of the arm D, extends under the wheel J, passing through a. slot in the upright F, and is then bent upwardly at iight angles, ending at a point near the top faire ol' the plate C. A depression, M', in the plate C, and a suitable perforation exposing the end ofthe spring M, cuables the user to press the spring downward and release the part L' from the notch K ou the under side ofthe wheel J. A depression, J', is also formed around the wheel J, and a transverse slot exposes the wheel so that it can be manipulated. v

rlhe ordinary glass spirit-level tube is placed within the tube H. The upper face ofthe metal tube being exposed permits the user to read the indications as with the common level.

rlhe set-screw L is designed to regulate the tube if out of level. The screw I permits the tube H to be withdrawn and replaced when broken. lVhen in use the tube rests in the level with the face up, as shown 5 but when not in use the spring M is depressed and the tube turned face downward, so as to prevent injury to the glass.

Having described my invention,what l claim as new is- The combination ot' the face-plate O, having the adjustable block E, the arms D F, and spring L', with the removable and revolving tube H, having the set-screw I and wheel J, as herein specified.
